Dismounting a Backup Image File

Once mounted, a backup image file remains mounted until explicitly dismounted or the system reboots. The Backup Image Dismount Wizard guides you through the process of dismounting. As part of the dismount process, you can:

• Save changes to writeable backup images.
• Shrink the volume so you can restore the image to a smaller drive.

Note: The Shrink Volume feature truncates the mounted backup image so that the file system ends at the last currently-allocated cluster. To reduce the backup image size as much as possible, use a disk defragmentation tool on the mounted image to consolidate file distribution within the volume and free up space at the end of the volume.

To dismount a backup image, follow these steps:

1. Open the Backup Image Dismount Wizard by doing one of the following:
• In the Tasks menu, click Dismount Backup Image.
• In the Disk Map tab, right-click a mounted backup image, then select Dismount Backup Image.
2. On the Mounted Backup Images page, select the backup image volume to dismount, then click Next.
3. (Conditional) On the Backup Image Dismount Options page, select if you want to:
4. Note: These options are available only if the backup image volume is writeable (see Backup Image File Mount Options).

Save Changes to Incremental File	Saves changes made to the mounted volume. Right-click the incremental file to save the modified backup image file using a different name.
Shrink Volume	Shrinks the volume so you can restore this image to a smaller hard drive. Note: This option is only available when dismounting a writeable backup image of an NTFS volume in Windows Vista or Windows Server 2008 (or later).

4. On the Backup Image Dismount Summary page, review the dismount details, then click Finish.

The wizard dismounts the volume.
